(21) The noise thereof was heard in the Red sea.--Literally, as in the margin, the Weedy, or Reed sea. The crash of the fall of Edom, the cries of the slaughtered people, were to be heard far off on the waters of the sea that washed its shores. Elath, on the Gulf of Akaba, was the sea-port of Edom (2Chronicles 26:2).

Verse 21. - Is moved; rather, quaketh (as Jeremiah 8:16). It is a pity that the Authorized Version has not preserved the present tense throughout the verse. The prophet seems to see his prediction realized before him. In the Red Sea; rather, beside the Bed Sea; comp. 1 Kings 9:26, "Eloth, on the shore of the Red Sea, in the land of Edom."

The earth is moved at the noise of their fall,.... Of the Edomites; whose fall was from the height of greatness and glory to a very low condition indeed; and as things, the higher they are from whence they fall, the greater noise they make, so it was with the Edomites; perhaps there may be some allusion to the falling of rocks and hills, with which Edom, abounded: this may respect either the noise and shout of the conquerors, when they fell; or the cry of the Edomites, when taken and destroyed; or the report of their destruction, when it came into the world; which struck the inhabitants of the whole earth with terror and amazement, so that they trembled at it; an hyperbolical expression, as Kimchi observes:

at the cry, the noise thereof was heard in the Red sea, or, "sea of Suph", or "weeds"; where weeds and rushes grew in great abundance, from whence it had its name. This is the Arabian gulf, which washed the shores of Edom, and was called the Red sea from thence, Edom signifying red. The meaning is, that the cry of the slain, or of the conquerors at the slaughter of them, should be heard to the borders of the land, to the sea shore, and by those in ships there; who should carry the report of it to each of the parts of the world.

Red Sea—a considerable distance from Idumea; though the district at the Elantic bay of the Red Sea originally belonged to Idumea, and the sea itself was called from Edom, that is, "red" (Ge 25:30, Margin). Others translate, "the weedy sea" (Margin), and derive the name, "Red Sea," from its red weeds; the former view is preferable.

49:7-22 The Edomites were old enemies to the Israel of God. But their day is now at hand; it is foretold, not only to warn them, but for the sake of the Israel of God, whose afflictions were aggravated by them. Thus Divine judgments go round from nation to nation; the earth is full of commotion, and nothing can escape the ministers of Divine vengeance. The righteousness of God is to be observed amidst the violence of men.
